:Momentary Power Loss and Restart disable
【1】:Momentary power loss and restart enable
If the input power supply due to sudden increase in supply demand by other equipment results
in voltage drops below the under voltage level, the inverter will stop its output at once.
When 07-00 =【0】.On power loss, the inverter will not start.
When 07-00 =【1】.Aafter a momentary power loss, inverter will restart with the same
frequency before power loss, and there is no limitation on number of restarts.
On power loss, as long as the inverter CPU power is not completely lost, the momentary
power loss restart will be effective, restart will be according to setting of parameters 00-02 &
07-04 and status of External run switch.
Caution: After any power loss if the Run mode is set to External by parameter 00-02=1 and if Direct
start on power up is also selected by parameter 07-04=0, please note that the inverter will run on
resumption of power.
To ensure safety of operators and to avoid any damages to the machinery, all necessary safety
measure must be considered, including disconnection of power to the inverter.

07- 02=【0】: The inverter will not auto restart after trips due to fault.
07- 02>【0】, 07- 01=【0】.After a trip due to fault the inverter will run with the same frequency
before power loss, and restarts after an internal delay of 0.5 seconds.
07- 02>【0】, 07- 01>【0】, After a fault trip the inverter will run with the same frequency
before power loss, and restart with a delay according the preset in parameter 07-01.
Note: Auto restart after a fault will not function while DC injection braking or decelerating
to stop
Note: this function is available just after a fault/error. This parameter cannot be used
after momentary power loss.
Range
【0】:Enable Reset Only when Run Command is Off
【1】:Enable Reset when Run Command is On or Off
07-03=0 Once the inverter is detected a fault, please turn Run switch Off and then On again to
perform reset, otherwise restarting will not be possible.
Direct Running on Power Up
Range
【0】:Enable Direct running after power up
【1】:Disable Direct running after power up

When direct run on power up is selected by 07-04=0 and the inverter is set to external run by
(00-02/00-03=1), if the run switch is ON as power is applied, the inverter will auto start.
It is recommend that the power is turned off and the run switch is also off to avoid possibility of
injury to operators and damage to machines as the power is reapplied.
